IMPROVEMENT IN N URSERY-CHAIRS.

Specification forming part of Letters Patent No. 190,800, dated May l5, 1877; application liled January 31, 1877.

To all whom it may concern Be it known that I, JOHN GoLBY WHEEL- ER, of Baldwinsville, county of Worcester, and State of Massachusetts, have invented au Improvement in Ghilds Chair, of which the following is a specification:

This invention relates to improvements in childs chair, and has for its object the production of a chair convertible at pleasure into a high or low chair.

The invention consists in the combination, with a low chair, of a separate chair-holding frame, provided with legs and with locking devices, to permit the low chair to be raised with relation to the holding-frame, and to -be there locked in position for a -high chair.

Figure l represents my improved chair in perspective; Fig. 2, a front view thereof; and Fig. 3, a section on line :c w, Fig. 2.

In the drawing, c denotes the seat of the childs chair, having a back, ,1), supported by suitable rods, and legs c, held together by suitable rounds d. The chair-holding frame is represented asY composed ot'` legs e e, held together by suitable rounds f g. The chair and frame are fitted together, so as to move vertically with relation to each other when the frame is upright. The legs of the chair are shown as tted toguideways in the frame. (See Fig. 3.) At the back of the frame (see Fig. 1) is a locking device, 2, composed of a spring, adapted to support the chair in an elevated position by reason of a pin or projection, 3, on the chair, that projectsover the shoulder of the spring. vWhen the low chair is at its lowest position the pin 3 is below the locking device 2; but when the chair is elevated the locking device will yield until the pin 3 passes above it, when it will ily out and retain the chair in an elevated position. Two or more locking devices may be employed, according to the height to which it is desired to place the seat a.. When the part 2 is forced back by hand the chair may be lowered.

The form of the locking device may he varied without departing from this inventionas, for instance, the leg ofthe chair might be provided with a catch to engage a notch in the frame, or vice versa.

The legs e may be provided with casters, if desired to make a rolling chair.

The chair-bottom is provided with a circular opening, closed by means ot' a slide, l, which may be removed to convert the chair into a nursery-chair.

The arms m are grooved to receive arms n ot' a table, o, provided with a rim, p, for toys or for food.

The chair is provided with a foot-rest, 1', as usual.

By arranging the frame outside the chair the latter may be elevated to a greater distance than if the frame were arranged in grooves in the chair-legs.

I claim- The chair-holding frame provided with the grooved corner-posts e and a locking device, in combination with the childs chair a b c, having its legs titted within such frame, and adapted to be adjusted therein to form a high or a low chair, substantially as described.

In testimony whereof' I have signed my name to this specification in the presence of two subscribin g Witnesses.
